It has been narrated on the authority of Hadrat Anas Ibn Malik (may Allah be pleased with him) that eighty persons from the inhabitants of Makka swooped down upon Allah's Messenger (may Allah's blessings and peace be upon him) from the mountain of Tan'im. They were armed and wanted to attack the Holy Prophet (may Allah's blessings and peace be upon him) and his Companions unawares. He (the Holy Prophet) captured them but spared their lives. So, Allah (The Glorified and the Exalted) revealed the verse:
"And It is He Who restrained your hands from them and their hands from you in the valley of Makkah after He had given you a victory over them." (48:24)
Muhammad (s.a.a.w.) preached to the people to trust in Allah (swt). His whole life was a sublime example of the precept. In the loneliness of Makkah, in the midst of persecution and danger, in adversity and tribulations, and in the thick of enemies in the battles of Uhud and Hunain, complete faith and trust in Allah (swt) appears as the dominant feature in his life. However great the danger that confronted him, he never lost hope and never allowed himself to be unduly agitated. Abu Talib knew the feelings of the Quraish when the Prophet (s.a.a.w.) started his mission. He also knew the lengths to which the Quraish could go, and requested the Prophet (s.a.a.w.) to abandon his mission, but the latter calmly replied,
"Dear uncle, do not go by my loneliness. Truth will not go unsupported for long. The whole of Arabia and beyond will one day espouse its cause." [Ibn Hisham, Sirat-ur-Rasul]
Muhammad (s.a.a.w.) was of a height a little above the average. He was of sturdy build with long muscular limbs and tapering fingers. The hair of his head was long and thick with some waves in them. His forehead was large and prominent, his eyelashes were long and thick, his nose was sloping, his mouth was somewhat large and his teeth were well set. His cheeks were spare and he had a pleasant smile. His eyes were large and black with a touch of brown. His beard was thick and at the time of his death, he had seventeen grey hairs in it. He had a thin line of fine hair over his neck and chest. He was fair of complexion and altogether was so handsome that Abu Bakr composed this couplet about him:
"As there is no darkness in the moonlit night so is Mustafa, the well-wisher, bright."
His gait was firm and he walked so fast that others found it difficult to keep pace with him. His face was genial but at times, when he was deep in thought, there there were long periods of silence, yet he always kept himself busy with something. He did not speak unnecessarily and what he said was always to the point and without any padding. At times he would make his meaning clear by slowly repeating what he had said. His laugh was mostly a smile. He kept his feelings under firm control - when annoyed, he would turn aside or keep silent, when pleased he would lower his eyes [Tirmidhi].
His dress generally consisted of a shirt, tamad (trousers), a sheet thrown round the shoulders and a turban. On rare occasions, he would put on costly robes presented to him by foreign emissaries in the later part of his life. [Ahmed, Musnad, Hafiz Bin Qayyim]
His blanket had several patches. [Tirmidhi] He had very few spare clothes, but he kept them spotlessly clean. [Bukhari] He wanted others also to put on simple but clean clothes. Once he saw a person putting on dirty clothes and remarked,
"Why can't this man wash them." [Abu Dawood]
On another occasion he enquired of a person in dirty clothes whether he had any income. Upon getting a reply in the affirmative, he observed,
"When Allah has blessed you with His bounty, your appearance should reflect it." [Abu Dawood]
He used to observe:
"Cleanliness is piety."
